Description

DESCRIPTION

Busbar system

[0001] The invention relates to a busbar system for connecting devices using an integrated contact protection base plate module.

[0002] The bus bars can include one or more bus bars for supplying power to electrical devices. The devices are arranged directly on the busbars or via adapter devices. Conventional busbar systems use busbars with a rectangular cross section for power transmission. The busbars can be mounted inside switch cabinets. Busbars are used for single or multiphase power systems. For multiphase power supplies, the busbars are conventionally arranged parallel to each other, with switching devices arranged on the parallel busbars by means of hooks or adapter devices. With conventional busbar systems, it is necessary to adapt the power transmission busbars in such a way that contact protection is provided by protective covers for a user at points where no switching device is mounted on the busbars. Conventional busbar systems therefore require considerable installation effort for the user, as not only does the switching device have to be mounted on the busbars, but additional electrically insulating covering elements must also be attached to the busbars. to protect the user. The fact that, depending on the size of the switching device mounted on the busbars, there are generally no adequate and accurate electrically insulating cover elements available to mount without gaps in the busbars further complicates the situation. In many cases, therefore, gaps or gaps remain between the switching device mounted on the busbars and the subsequently mounted protective insulating cover elements. Due to the presence of the resulting gaps, the protection against accidental contact for a user or installer is reduced, so that there is a risk that an installer could come into contact with a working busbar under the insulating covers and receive an electric shock if careless handling is done.

[0003] Document EP2863496 Al describes a contact protection system for busbars with flat design contact protection modules, each comprising retaining feet to engage behind the busbars and hooking elements for mutual engagement with adjacent contact protection modules, where the contact protection modules for each bus bar have a terminal receiving area for receiving terminals that are provided to make electrical contact with the respective bus bar.

[0004] Therefore, an objective of the present invention is to provide a busbar system that offers a user a higher level of operational safety and that can be easily installed.

[0005] According to the invention, this objective is achieved by means of an energy busbar system with the characteristics defined in patent claim 1.

[0007] A further advantage of the power busbar system according to the invention is that the devices can be attached to the contact protection base plate module without tools, since the devices have spring-loaded contacts that engage the modules of bus bars. A further advantage of the energy busbar system according to the invention is that the busbar system can be installed particularly easily and quickly, since the contact protection base plate modules with the integrated busbars are already preconfigured and, therefore, the user does not have to individually install the busbar modules and the busbars. The base plate module can be mounted on different mounting rails (flat and tall version) of the switch cabinet. Due to the special design of a double acting latch mechanism, the base plate module can be mounted vertically and does not need to be tilted. This is particularly advantageous for a large motherboard module (eg a 5-pole system or system with add-on modules). As an additional mounting option, the base plate module can be screwed to a mounting plate in the control cabinet.

Furthermore, the various devices to be connected, in particular the switching devices, can be easily arranged directly on the contact protection base plate module from the front and inserted vertically from the front into the busbars of power provided within the touch protection motherboard module. Therefore, the devices can be frontally arranged on the touch protection base plate module without a tilting movement and inserted with a single movement into the contact grooves of the contact aperture distribution of the devices. electrically conductive busbar modules.

The lower part 3 of the base plate module 1 has a groove or contour 10 for positioning the contact protection base plate module 1 on a mounting rail 23. This groove runs centrally in the center in the longitudinal direction of the plate module base 1, as shown in figure 11. Base plate module 1 can be arranged on a mounting rail, in particular a DIN rail, and subsequently hooked onto the mounting rail. For this purpose, the lower part 3 of the touch protection base plate module 1 has several latching elements 17, as shown in figure 11. In the embodiment shown in figure 11, the base plate module without Contact 1 has four hooking elements 17-1, 17 2, 17-3, 17-4 provided for a mounting rail 23 at its rear.

Four adjacent hooking elements 17-i are visible, which form fastening means 10 for hooking to a rail mounting 23, in particular a DIN rail. Figure 12 shows a basic module with four additional modules. The coupling element is extended with extension elements. Figure 13 shows a perspective view of the hook element 17-4 shown in figure 12, which is identical to the other three hook elements 17-1, 17-2, 17-3, with extension elements of the hitch element.

[00094] Figure 14 shows a rear view of the latch 17-i shown in figure 13. The latch 17, which is used to mount the contact protection base plate module 1 on a rail of mounting, has a bias lever 18, which is molded into latch 17 by means of a meander-shaped connection 19 and has a central support point. The latch element 17 also has integrated return springs 20, 21. Alternatively, an external spring action by compression springs is also possible. Furthermore, the latch element 17 has an operation point 22 to be operated by a user or operator. The latch 17 is adapted such that the bias lever 18 inserted into the latch 17 deviates an operating movement from one side in such a way that both DIN rail latches are released from the corresponding DIN rail. The bias lever 18 is mounted on a shaft of rotation. On the latch element, latch hooks 24A, 24B are provided which, when locked, engage behind the DIN rail or mounting rail 23 so that the touch protection base plate module 1 cannot be removed from the mounting rail or DIN rail 23. If the latch 17 is operated or pulled in the area 22 with a screwdriver, the formed latch hook 24B moves evenly downward and at the same time, the diverter lever 18 rotates out of the center position symmetrical shown in figure 14 around the axis of rotation, where the other hook 24A moves in the opposite direction, so that the contact protection base plate module 1 can be removed from the DIN rail or mounting rail 23. If the latch is pulled further, the latch engages in a park position so that the user must actively push the latches back into the locked position when returning to the park. ontar them. The fasteners 10 formed by the latch elements 17-i can be easily operated by a user by actuating the operating points 22 located on the edge of the contact protection base plate module 1. An advantage of the double-sided latch element is that the motherboard module 1 can be front mounted on the DIN rail without tilting. This means that even very tall motherboard modules 1 can be mounted without problems.

[00095] Figures 15A, 15B, 15C, 15D show a contact protection base plate module 1 mounted on a mounting rail 23 from the rear and from the side. In the exemplary embodiment shown in Figures 15A, 15B, 15C, 15D, the base plate module 1 has three latching elements 17-1, 17-2, 17-3. In the exemplary embodiment shown in Figure 15, the operating points 22 of the latching elements 17-i are provided at the upper edge of the basic touch protection module 1. Depending on the environment and context, the points of Contact 22 of the latching elements 17-i may be provided on the upper or lower edge of the contact protection basic module 1 to facilitate operation by a user. The hooking elements 17-i allow front mounting and re-removal of the contact protection base plate module 1 on the mounting rail 23 without tilting. The latching elements 17-i can be operated with or without the use of a tool. The mounting rails 23 can have different mounting rail heights in different embodiments. The advantage of operating the latching elements 17-i is that they can be operated without disassembling devices or products from the contact protection base plate module 1. In one possible embodiment, the latching function of the latching elements 17-i has a parking position. The mounting rail 23 is attached on both sides by the hooking elements 17-i in the hooked state. The direction of movement of the latch tabs is preferably deflected by an inclination mechanism of the latch element 17. In a possible embodiment, the operational function is transferred to the respective additional element when the contact protection base plate module 1 is inserted or the crossbars. The number of latching elements 17 required depends on the size or length of the contact protection base plate module 1 and the size or weight of the devices 11 mounted or mountable on it. The more devices 11 are mounted on the base plate module 1 and the greater their expected weight, the greater the number of latches 17-i mounted on the rear of the touch protection base module 1.
